| Abstract |
This work presents a buck quasi-resonant zero-voltage-switching converter controlled by pulse-width modulation. This topology incorporates to conventional quasi-resonant converters the well-known advantages of constant-frequency operation. The pulse-width modulation is achieved by the introduction of an active switch in the resonant tank. The added switch operates with zero-current switching, thereby not adding significative dissipative losses to the converter. Principle of operation, steady-state analysis, simulation and experimental results are presented. Advantages and shortcomings of the topology are discussed and a family of PWM ZVS QR converters is proposed. |
